Perhaps you can improve on it and adapt it for you usage: if($u->birthday) { ereg("([0-9]{4})-([0-9]{2})-([0-9]{2})", $u->birthday, $br); // $birthday = date("D,Md,Y", mktime(0,0,0, $br[2], $br[3], $br[1]) ); ereg("([0-9]{4})-([0-9]{2})-([0-9]{2})", date("Y-m-d", time()), $today); for($i = 1; $i < 4; $i++) { settype($br[$i], "integer"); settype($today[$i], "integer"); } $age = $today[1] - $br[1] - 1; if( ($today[2] > $br[2]) || ($today[2] == $br[2] && $today[3] >= $br[3]) ) $age = $age + 1; $username .= "/{$age}"; // $username .= "(<FONT SIZE=-1>{$birthday}</FONT>)"; >__________ Get more from the Web.
